FreedomPop uses Sprint’s network. They have a free tier of service that includes 200 minutes, 500 texts, and 500 MB of 4G LTE data. $20 monthly will get you unlimited talk and text plus 1 GB of 4G LTE data, which isn’t too bad in its own right. Similar to Republic, FreedomPop will get you on Wi-Fi as much as possible. The difference here is that you can earn more data by pestering your friends to join FreedomPop or doing ad-related actions — savings, like money, don’t grow on trees. Also, keep in mind you’ll need to purchase a device through FreedomPop or bring your own Sprint phone.
Ultra Mobile uses T-Mobile’s network. Their $29 unlimited international plan gives you unlimited talk, text (including MMS), and 1 GB of 4G LTE data, plus unlimited global text and international calling to 71 countries. They’ll also throw in 1,000 international minutes to use to call 18 other countries, plus $2.50 worth of credit for the other 109 or so countries. Like a lot of other plans on this list, you only get that 1 GB — after that, no data. To get unlimited data at 3G speeds, you’ll have to go up above our $30 limit.
